This application is a continuation of U.S. patent application Ser. No. 15/221,560 entitled “Interchangeable Truck Bed” and filed Jul. 27, 2016 for Greg Stocks and Thomas Mudge, which claims the benefit of U.S. Provisional Patent Application No. 62/197,527 entitled “Interchangeable Truck Bed” and filed on Jul. 27, 2015 for Greg Stocks and Thomas Mudge, both of which are incorporated herein by reference.

FIELD

This invention relates to truck beds and more particularly relates to interchangeable truck beds using a locking mechanism.

BACKGROUND

When a truck is received from a manufacturer, the truck usually has one truck bed attached to the chassis. The truck bed is usually not removable. Additionally, the truck bed is usually limited to one or only a few functions.

However, many truck owners and operators have multiple uses for their trucks. These uses may include construction, hauling equipment, hauling materials, farming, transportation, or the like. Unfortunately, since most trucks have only one bed, truck owners and operators often purchase multiple trucks for the different uses. This may require a truck owner and operator to refuel, maintain, and register each individual truck, which can be very costly.

SUMMARY

The system 100 may include a seal 122. The truck 102 may include the seal 122. In certain embodiments, the seal 122 may include a pan, a plate, a ring, or the like. The seal 122 may include a seal formed or shaped in the shape of the front of the truck bed unit 110, the back of the cab of the truck 102, or the like. The seal 122 may be disposed at the front of the truck bed unit 110 and protect the front of the truck bed unit 110 from scratching, scraping, and the like the truck 102. The seal 122 may prevent water, dust particles, and the like from entering the space between the truck 102 and the truck bed unit 110.

In one embodiment, the truck bed unit 110 may include the one or more extensions 116 and the truck chassis 108 may include the one or more receiving mechanisms 118. The one or more extensions 116 connecting the truck bed unit 110 to the truck chassis 108 may include retracting the extensions 116 and pulling the truck bed unit 110 toward the truck chassis 108.

FIG. 1B depicts one embodiment of a system 100 for an interchangeable truck bed. The system may include the truck chassis 108. The truck chassis 108 may include the one or more extensions 116. The one or more extensions 116 may be arranged on the chassis with two or more of the extensions 116 lateral to the chassis and two or more of the extensions 116 longitudinal to the chassis.

While the embodiments are described herein primarily with regard to full-size road and utility vehicles, in certain embodiments, a truck 102 and a truck bed unit 110 may comprise a miniature toy, such as an injection molded plastic or die-cast metal toy; a remote control toy (e.g., with various interchangeable truck bed units 110 such as a squirt gun unit 110 with a trigger, button, or other interface on the remote control to squirt the water; a walkie-talkie unit with a speaker that projects audio from a microphone of the remote control unit 110; a bulldozer unit 110 that actuates in response to a command from the remote control; a dump truck unit 110 that actuates in response to a command from the remote control; a seating unit 110 for children, for action figures, for stuffed animals, or the like; and/or another remote control unit 110); a model; a ride-on toy for children (e.g., scoot powered, with pedals to mechanically power one or more wheels, with an electrical motor, with a fuel engine, or the like); and/or another type of truck 102 with one or more interchangeable truck bed units 110 that are smaller than full-size. The receiving mechanisms 118 and/or extensions 116, in certain embodiments, may be different for a toy or other smaller truck 102. For example, the extensions 116 and or receiving mechanisms 118 may comprise one or more magnets, a hook and loop fastener, a tension fit, complimentary interlocking extensions 116 and receiving mechanisms 118, or the like, which may not be configured for use with a full-size, road, utility truck 102.

In a further embodiment, a truck 102 and interchangeable truck bed unit 110 paradigm may be visually and/or virtually depicted in a paper or electronic book, in a video game, or the like. For example, in a video game, a player may drive a virtual truck 102 and may use different interchangeable truck bed units 110 to accomplish different tasks within the video game; in a book or video game, a player may place one or more different interchangeable beds in order, in place within an equation, in a blank within a word, or the like to solve educational questions or problems; or the like. Use of an interchangeable truck bed paradigm in toys, video games, books, or the like, in certain embodiments, may serve as advertising for or to improve brand recognition for full-size, utility trucks 102, in addition to providing educational and/or entertainment value.

In one embodiment, the one or more extensions 116 may connect to the truck bed unit 110 in response to the transmission of the truck 102 being in “Park” or in “Neutral,” or in response to engaging the emergency/hand brake of truck 102. In one embodiment, the one or more extensions 116 may disconnect the truck bed unit 110 in response to the transmission of the truck 102 being in “Park” or in “Neutral,” or in response to engaging the emergency/hand brake of the truck 102.

In one embodiment, the one or more extensions 116 may prevent the transmission of the truck 102 from changing gears (e.g. from “Park” to “Drive,” “Neutral” to “First Gear,” or the like) in response to the one or more extenders 204 being extended. The one or more extensions 116 may prevent the extenders 204 from extending in response to the transmission of the truck 102 being in a movable gear (e.g. “Drive,” “Reverse,” “First Gear,” and the like).

In one embodiment, the system 200 may include a manual override that may allow a user to use the one or more extensions 116 to connect the truck bed unit 110 to the truck chassis 108. The manual override may allow a user to use the one or more extensions 116 to disconnect the truck bed unit 110 from the truck chassis 108 without a power source.
